The U.S. Environmental Protection Agency has certified Daimler Trucks North America’s complete portfolio of model year 2013 on-highway, vocational and medium-duty vehicles as fully compliant with the new greenhouse gas 2014 regulations, Daimler said today, Feb. 23.

DTNA’s GHG14 compliance came a year ahead of the mandate for certification by the EPA and the National Highway Traffic Safety Administration’s first-ever program to reduce heavy- and medium-duty truck greenhouse gas emissions. Under the new GHG14 regulations, trucks and buses built in 2014 through 2018 are projected to reduce oil consumption by 530 million barrels and greenhouse gas emissions by 270 million metric tons.

“DTNA is committed to working with EPA and NHTSA to address critical issues facing the United States such as greenhouse gas reduction, as well as dependence on foreign oil,” said Martin Daum, president and chief executive of DTNA.

NHTSA and EPA designed the GHG14 standards to address global climate change, as well as to improve fuel efficiency thereby reducing oil consumption. The effect of these actions will be to improve energy security, increase fuel savings, reduce GHG emissions, and provide regulatory certainty for manufacturers.
